If you recently added security information to your Microsoft account, you may need to verify it. This verification process tells us that you, not someone trying to steal your account information, made the changes. Here's how to verify your security information:

If you need to verify your security information, you'll see the word Verify under the phone number and/or email address. Click Verify.

Sign out of your Microsoft account, and then sign in again.

Try to sign in to Xbox Live on your console again.

Solution 4: Clear the system cache

If you recently changed your password or security information on your Microsoft account, you may need to clear the cache on your console to remove any previously saved information.

Press the Guide button on your controller.

Go to Settings and select System Settings.

Select Storage or Memory.

Highlight any storage device, and then press Y on your controller. (It doesn't matter which storage device you select; this will clear the cache for all storage devices.)

Select Clear System Cache.

When prompted to confirm storage device maintenance, select Yes.

Solution 5: If you recently signed up for two-step verification, create a unique app password in your Microsoft account

To see if your account has two-step verification turned on, sign in to your Microsoft account and select Security info.

If you recently turned on two-step verification, you may not know how to sign in to apps or devices that don't accept security codes. Some apps (like the mail apps on some smartphones) and devices (like the Xbox 360) can't prompt you to enter security information when you try to sign in.

If you have two-step verification turned on and get an "incorrect password" error with an app or a device, you'll need to create a unique app password in your Microsoft account associated to that app or device before you can sign in. You'll need to do this for each app or device that can't prompt you for security information.
